This aircraft is believed to be AS-04 based on what appears to be a partial number 4 on the rear fuselage where Indonesian Gannet serials were located. Gannet AS-14 was retained in the UK for training and reputedly never in Indonesian markings. It was returned to the Royal Navy. The meaning of III or 111 on the fin is not known but it was on all Indonesia Gannets, which were operated by 100 Squadron
